My mother was Rebecca Ida Zaretsky (maiden name) from Minsk Russia.I have no other information on her.What ship she came over in etc. She supposedly came over in 1911 with her mother and father. Her mother's name was Pearl. Her other brothers and sisters were already here in the U.S. Her siblings were: Harry, David, Sarah, Anna, Jenny, Benjamin, ???? Not sure if there were more. I know I have relatives in New York and California. Anyone who can give me any help would be appreciated. If anyone is related to me and would like to correspond via email, I would appreciate that. Thanks
